Clinical Trial Summary

Rationale: Recently our study group reported the results of the Basilar Artery International Cooperation Study (BASICS), a prospective registry of patients with an acute symptomatic basilar artery occlusion (BAO). Our observations in the BASICS registry underscore that we continue to lack a proven treatment modality for patients with an acute BAO and that current clinical practice varies widely. Furthermore, the often-held assumption that intra-arterial thrombolysis (IAT) is superior to intravenous thrombolysis (IVT) in patients with an acute symptomatic BAO is challenged by our data. The BASICS registry was observational and has all the limitations of a non-randomised study. Interpretation of results is hampered by the lack of a standard treatment protocol for all patients who entered the study.

Objective: Evaluate the efficacy and safety of IAT in addition to best medical management (BMM) in patients with basilar artery occlusion.

Study design: Randomised, multi-centre, open label, controlled phase III, treatment trial.

Study population: Patients, aged 18 years and older, with CTA or MRA confirmed basilar occlusion.

Intervention: Patients will be randomised between BMM with additional IAT versus BMM alone. IAT has to be initiated within 6 hours from estimated time of BAO. If treated with as part of BMM, IVT should be started within 4.5 hours of estimated time of BAO.

Main study parameters/endpoints: Favorable outcome at day 90 defined as a modified Rankin Score (mRS - functional scale) of 0-3.
